Hi All, I have discovered a Ubuntu Boot-Repair -Disc which avoids syntax issues, I was unable to come up with a satisfactory syntax for the commands needed to solve this problem. Suitably chastened I have located a laptop which has Thunderbird so now I can keep the thread on the list. My attempts to communicate from a tablet produced a pile of crap. I downloaded and burned a Disk-Repair-Disk for Ubuntu I have run the recommended steps to repair GRUB 2.8, but nothing has been achieved. I did request the log be sent to a paste bin just in case, and as it is a few pages of text here is the link. http://paste.ubuntu.com/p/pNsZCYF5QZ/ The last line acknowledges the failure to achieve a result. This machine is critical to my work, and I had considerable assistance earlier in 2019 to achieve a RAID system on this machine, for which I am truly grateful. I would appreciate any assistance with this problem. Andrew Greig
